Abstract:Objective To evaluat the application value of gender determination in forensics by screening measurement da‐ta of bony quantitatively by cephalometric .Methods 129 cases were randomly selected according to the inclusion criteria . 28 osseous indicators(N‐S ;S‐Ba ;Pcd‐S ;S‐Ptm ;N‐ANS ;ANS‐Me ;A‐Ptm ;S‐Go ;Pog‐Go ;UI to NA length ;LI to NB length ;N‐S‐Ar ;S‐Ar‐Go ;Ar‐Go‐Me ; ∠ SNA ; ∠ SNB ; ∠ SND ;PP to FH ;FH to SN ;MP to SN ;FH to N‐Pog ;Y‐ax‐is angle ;NBa‐PtGn ;UI to LI ;UI to SN ;LI to MP ;UI to NA ;LI to NB) were quantitatively measured ,and the discrim‐inant analysis was conducted by Fisher discriminant method and Cros‐validated(a) method for discriminatory analysis and evaluation .Results The introduction of gender discrimination formula had a variable L5 :N‐ANS in 129 cases were ran‐domly selected ,and it was concluded that discriminant function for Y was ‐20 .398 + 0 .386(L5 :N‐ANS) .Conclusion In this study ,the measurement data of cephalometric in the head side is a measurement for N‐ANS ,which can be used for gender determination .Total coincidence rate is 84 .5% .
